Application filed July 1, 1916. Serial No. 107,060.

' tols; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention has for its object to providean improved firearmincluding a novel cartridge holder or magazine supported in thepistol handle and having two chambers each adapted to receive a supplyof cartridges, whereby the cartridge capacity of pistols of this type ispractically doubled.

Another object is the provision of means for controlling the projectionof the car-' tridges from the two cartridge chambers to the firingchambers. v

\Vith these and other objects in view, the invention consists in thenovel construction. combination and arrangement of parts as Will behereinafter specifically described, claimed and illustrated in theaccompanying .drawings, in which:

Figure 1 represents a side elevation of the improved fire arm, Fig. 2represents a bottom plan view thereof, Fig. 3 represents a longitudinalsectional view through the pistol, Fig. i represents a sectional viewthrough the double Cartridge holder or magazine removed from the handleof the pistol, Fig. 5 represents a front elevation of the barrel of thepistol, Fig. 6 represents'a' longitudinal sectional view on the line P43of Fig. 3, and Fig. represents a transverse sectional view on the line7-7 of Fig. Referring to the drawings in detail, wherein similarreference numerals designate corresponding parts throughoutthe severalviews, the numeral 10 indicates the body of the pistol, which includesthe trigger guard, hollow handle 11 and integral upstanding block 12. Apivot pin 13 is insorted through the forward extremity of the body 10and pivotally connects the forward portion'of the barrel 1i therewith,the rear terminal of the barrel being detachably connected with theupstanding block 12 by a detachable pin or bolt 15. The barrel H isformed with two longitudinal bores 16 and a spring-receiving opening 17arranged centrally above and parallel to the bores 11'.

. The bolt of the pistol includes the breech block 18 slidablv mountedin the chamber 11) in the body 10 rearwardly of the barrclll andconnected with a substantiallv U-shapcd guide member .30 slidablymounted upon the body 10.

The bolt 18 is nori'nallv retained in cngagcment with the rear terminalof the barrel 14. by the tension of an cxpansiblc spring 21 arranged inthe chamber 17 and confined between a shoulder 22 and the head '13 of arod 2l,'pivotall v conncctcd at 25 with the sliding bolt 15. A pivotedlocking member :24 is mounted in a recess ffll'llltril in the bolt 18and is adapted to cngagc in a rcccss formed in the rcarwardly extendingportion of the barrel 14 to lock the bolt against operation. The lockingmcmbcr 24 may bc conveniently operated by the user by means of a button2 carried by the sliding guide :20 of the breech bolt in.

The bclt lb is providcd with two spaced firing pins 27 arranged inalimuiiciit with the bores 16 and normally relaincd in rearwardlyextended positionlrv the tension of springs :2

The hammer mechanism comprises a pair of hammers 3U, pivotallv moun cdat ll in matically set in thc usual manncr b v thc rccoil movcmcnt ofthe bolt l Each hammer 30 is connected by a link 3; with one of a pairof rods 33. slidahlv mountcd in a chamber 'i-i formed in thc lowcrportion of the handle ll. hcn rclcascd. lhc lininmcrs 30 areautomatically thrown forwardly against the rear terminals of the liringpins 27 by the tension of springs conlim-d in the chambers 34 bctwccnthc heads :in of lllc rods 33 and shoulders 37 formed intcrnullv of thechambers -H. The lowcrterminals of the chambers -H are normallv closedbv removable plugs 38. I

The upper edge portions of'thc hammers 30 are concavcd, as indicated at3 and adapted to engage a shaft or bolt 40. non

rotatablv and slidablv mounted in the rear therethrough. liy theprovision of the shaft 40 with a singlerecess 41 therein, one of the-hammers 30 is always held in inoperative position. However, either oneof the hammers may be released, for operation, by so adjusting the shaft40 as to swing rear.

4 wardly and downwardly through the recess 41.

The sprin actuated trigger 43 is connected with the ody 10 and isadapted to actuate the sear 44 mounted in the handle 11 and normallyretained in engagement with the rod 33 'by;the tension of a leaf spring45 confined inv the handle 11. Thc'tooth ofthe sear-44=is adapted toengage ina recess, 46

for the rod 33 to 100k the latter in elevated position against action ofthe spring The trigger 43 maybe locked against operation by atriggersafety lock 47 mounted injthef body 10- rearwardly of the triggerv 43.

-The magazincyor"cartridge holder, illustrated in detail in Fig. 4comprises a body 48 having two cartridge-receiving chambers 49 thereinin which is received asupplyof cartridges 50, which arenormally pressedtridges in either chamber V which is locked by t-hesear44.- The stop-Tplate at the left side of the pistolis ad-" justed so asto prevent theprojection of the upwardly withinthe holder 48 by thc'ten- 'sion ofsprings Z 1.- The holder 48 is adapt ed for insertion in the hollowhandle 11, in the usual mannery and is locked in position in the handleby a catch 52*. The projection of-the cartridges 50 from either chamberof the holder 48 to the corresponding bore 16 of the double barrel iscontrolled by stop plates 50, slidably mounted in slots 51 formed in theopposite sides of the body 10 and coin nectedwith buttons 52,arranged"exteriorly of the body whereby the plates'oO may beconveniently operated to permit the carproper bore 16.

In use, the shaft 40 is adjusted so as t0 release the right hand'hammer30 and the cartridge holder 48 having a supply ofcartridges 50 in eachchamber 49 is inserted in the handle 11' The breech bolt 18 and guidemember 20 are subsequently moved rearwa-rdly, thereby setting the hammer30 cartridges contained therein" into the left hand bore 16 and thus byactuatingthetrigger 43 the. cartridges in the right hand chamber ofthecartridge cessively fired. I

IVhen the supply of cartridgesi'n the right hand chamber of the holder48 is ekhausted, the shaft 40 is-moved to'the left} subsequent to movethe breech bolt- 18andguide member 20 rearwardly, thus permitting theleftiholder are su'chand hammer 30 to move freely througl iithe" recess41- and lock the right hammer 3 0 in inoperative-position= The left handStQP plate 50 :is subsequently adjusted s6 asto' permit the, pro ectionof the' cartridges into the left hand bore 6 of the barrel.
